APPARATUS FOR HANDLING FORGINGS.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed December 16, 1908. Serial No. 467,792.

To all whom it may concern:

Be it known that I, ROBERT F. DEVINE, of Erie, Erie county,Pennsylvania, have invented a new and useful Apparatus for HandlingForgings, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a sectional plan viewof one form of apparatus embodying my invention, the section being takenon the line II of Fig. 2; Figs. 2 and 3 are vertical sections takenrespectively on the lines IIII and III-III of Fig. 1; Fig. 4 is asectional plan view of the trolley and smaller turntable, the sectionbeing taken on the line IV-IV of Fig. 2; and Fig. 5 is a detailsectional view showing the cylinder and the hub or support therefor; andFig. 6 is a sectional plan view, showing a modification.

vMy invention has relation to apparatus for handling forgings during theheating and forging operation, and is designed to provide means of thischaracter by which the piece to be forged can be transferred from thefurnace to the forge and properly manipulated under the action ofheating, forging or pressing, the apparatus being so arranged as toprovide for the full control of the piece under the hammer, press andfurnace, and to enable it to be manipulated by the apparatus withsubstantially the same control as in hand forging.

A further object of the invention is to provide apparatus of thischaracter, which will be capable of handling pieces or forgings ofvarious shapes and sizes.

The nature of my invention will be best understood by reference to theaccompanying drawings, in which I have shown the preferred embodimentthereof, and which will now be described, it being premised, however,that various changes may be made in the details of construction andarrangement of the parts without departing from the spirit and scope ofthe invention as defined in the appended claims.

In these drawings the numeral 2 designates the base of the apparatus,provided with a circular support 3, bolted to the lower part of acircular track 3 and supporting the upper part 1 of a circular track fora turntable having the wheels which travel between the tracks 81 and 4said turntable having also a central bearing at 5 upon which it turns.

7 designates suitable bracing for the turntable, and 8. arediametrically extending tracks which form the body of the turntable, thewheels 6 being carried by frame end braces 6 of tracks 8 and bearings 6bolted with I-beam braces 7. These tracks as shown in Figs. 2 and 3,consist of upper and lower pairs of rails between which are mounted thewheels 9 of a carriage or trolley 10, said carriage or trolley beingfreely movable upon said tracks. This carriage carries a table 11, uponwhich is mounted a second turntable 12, preferably upon ball bearings13.

Rising from the table 12 are the four posts or columns 14:. 15 are twocross-heads or slides, each mounted to slide vertically on thesecolumns, and which are provided with bearings 16 for the trunnions 17 ofa hub or carrier 18 of a work holder or cylinder 19. The cylinder 19forms the holder for the piece to be forged, and may be of the characterdescribed. and claimed in my Patent No. 740,100 of September 29,.1903,to which reference may be had for a more complete description thereof,or it may consist of suitable tongs 19, such as shown in Fig. 2, andwhich form the subject matter of my application, Serial No. 467,791,filed December 16, 1908. This cylinder is mounted to slide endwisethrough the hub or carrier 18, and also to rotate therein, the hub orcarrier being provided with one or more sets of anti-friction rollers20, against which the exterior of the cylinder bears. The cylinder isrotated on these bearings by means of a worm gear wheel 21 driven by anelectric motor 22 through the reduction gearing 23.

24: designates springs, which are coded around the trunnions 17 betweenthe hub or carrier 18 and the cross-heads or slides 15. The bearings 10are in the form of sleeves, which are extended through the slides 15 andwhich engage slotted arms or housings 25, to which are attached the endsof chains 26. These chains pass upwardly and over toothed wheels on atransverse shaft 27 j0ur naled at the top of the posts or columns 1 1,and thence downwardly and around toothed wheels 27 at the base of thecolumns, one end of each chain being attached to the arms 25 above thetrunnions 17, and the other end of each chain being attached to saidarms below said trunnions. The shaft 27 is arranged to be driven by anelectric motor 28 supported on a frame 29 secured to the tops of theposts or columns 14.

3O designates springs sealed in the slots of the arms or housings 25 andwhich cooperatewith the springs 24 before referred to to prevent thethrusts of the forging hammer from being transmitted to the other partsof the apparatus.

The main turntable is revolved through the desired angle by means of themotor.

31 having a pinion 32 driven through the intermediate gearing 33 andengaging the teeth of the rack 34 bolted to lower circular track plate 3The carriage or trolley 10 is reciprocated on the tracks 8 by means of amotor 36 mounted thereon, and geared to a winding drum 37 around whichis wrapped the ends of oppositely extending cables 38, the other ends ofthese cables being connected to the truck wheel frames 6' of theturntable at opposite sides of the machine, as shown in Fig. l.

The operation will be readily understood.

The main turntable is operated to bring the cylinder 19 into position toreceive from the furnace the piece to be forged and to carry it to theforging machine, press or hammer. The motor 36 is then operated to movethe carriage or trolley 10 to the desired position on the tracks 8.Smaller angular movements of the piece are effected by turning thesmaller turntable 12. The piece is raised and lowered by the operationof the motor 28, and is rotated for rounding up by means of the motor22. For heavy pieces, the main weight of the piece will preferably becarried by a supporting chain 39 from a suitable overhead crane or othersupport, as in hand forging, and the motor 28 can then be operated totilt or tip the piece in a vertical plane. These several movementsprovide for perfect control of the piece to be forged, which can be ofvarious sizes or shapes, and can, by a proper combination of movementsbe manipulated by the apparatus with the same freedom as in handforging.

Instead of mounting the apparatus upon a turntable in the mannerdescribed, the carriage or trolley 10 may be mounted upon rails 40 (seeFig. 6), constituting a cranebridge, and mounted on wheels 41 whichtravel 011 tracks 42 at right angles to the rails 40. The apparatuscarried by the carriage or trolley 10 is the same as that shown in theother figures. The cables 38 are in this case connected to the truckframes 43 at the ends of the tracks 40. Upper and lower rails 40 arepreferably employed between which the wheels 9 of the trolley orcarriage travel. The bridge formed by the rails 40 is moved on thetracks 42 by means of a motor 44. The shaft of the motor carries apinion 45 whichmeshes with a gear wheel 46 on a shaft 47. On each end ofthis shaft 47 is a pinion 48 which meshes with a gear wheel 49 attachedto the axle of one of the wheels 41. In this construction, the transfermovements are obtained by moving the apparatus longitudinally on thetracks 42, and angular movements by means of the turntable 12.

It will be understood that I do not limit myself to the use of thecylinder 19 asthe means for supporting the work, since this may be ofany desired character.

Various other changes may be made in the details of construction andarrangement of the parts without departing from my invention.
